Chapter 39 Working in the Environment 861
The position (and existence) of the first two layers—All Objects and Global Objects—is
protected, and they can not be deleted:
 All Objects: This layer displays all objects in the Environment. The objects in this layer
are normally shown as a list.
 If you turn off the Logic Pro > Preferences > Display > Other > “Allow ‘All Objects’
layer” option, the All Objects layer will disappear from the Layer menu. Enable this
preference if you need access to the All Objects layer.
 You can choose the Options > Go to Layer of Object command, in the Environment
menu, to switch to the selected object’s layer.
 Global Objects: You can place objects that you want to be visible in all layers in the
second layer from the top. These will appear at the same position in all layers. It is
recommended that you place as few objects as possible on this layer, due to the on-
screen clutter that global objects can create.
